My bank site uses them for logging in and they used to work properly in 5.0.x but stopped working in 5.1.x (when I pressed a key, they would always jump to z and nothing else) and continues not to work in 5.5. However, this also occurs in Safari/WebKit...

Another example of where it doesn't work in 5.5 that everyone can test is the Forum Jump menu at the bottom of the page here - no matter what key you press it always jumps to "Who's Online" which is also the case in WebKit/Safari.
